. Two chambers are control systems completely independent from each other,and each is provided with a controller, thus forming two systems that can start and stop independently;.

. Two different test conditions can be executed simultaneously，which improves testing efficiency;

. An advanced refrigeration control technique to improve efficiency and ensure the stability of the compressor during long-time running;

. A compact case design substantially reduces the floor space of the case and saves the space ofthe laboratory;

. Various options are available, and the test chamber can be upgraded for different samples.
